摘要：

Glasses with the compositions in mol % of 50ZnO:(50 - x)B2O3:0.5Eu(2)O(3):xWO(3), x = 0, 1, 3, 5 and 10 were obtained by applying the melt-quenching method and investigated by Raman spectroscopy, DSC analysis and photoluminescence (PL) spectroscopy. Raman spectra revealed that tungstate ions incorporate into the base zinc borate glass as tetrahedral [WO4](2-) groups, and octahedral [W & Oslash;O-4(2)](2-) species with four bridging and two non-bridging oxygen atoms. There are also metaborate, [B & Oslash;O-2](-) and pyroborate units, [B2O5](4-), in the glass networks. The glasses are characterized by good transmission in the visible region, at about 80%. Photoluminescence (PL) spectra evidenced that WO3 is an appropriate constituent for the modification of zinc borate glass structure and for enhancing the Eu3+ luminescent intensity. The most intense luminescence peak observed, at 612 nm, suggests that the glasses are potential materials for red emission.
